Last Chapters

In the last two chapters of world war z we figure out what the governments of the world do to finish the zombie hunting days.  This is when the solution to the problems are implemented rather than only being talked about among each other.  There are also clean-up operations to rid cities of bodies so that the cities look nicer.  In the goodbyes chapter its not literally goodbyes.  The interviewer is mainly seeing where people have settled down after the war.  He just wants to know what they are doing now that everything bad that has happened is over.
